This movie came on TCM last night and there was no way I could turn it off. While part of me likes it for the cheesy 70s computers, I must admit that this is far “smarter” a thriller than comes out of Hollywood these days — especially those by Mr. Crichton. While the plot is exactly the same as Crichton’s later “Jurassic Park,” there is a wonderful intratextuality about “playing roles” that is oh so 70s and heavy. The “kill” scenes are right out of Peckinpah because it is all, like, why kill, man? There is definitely a feel to this film (as with another film Crichton directed, but did not write, called “Coma” from 1978 — should the guy haved stayed a director?) Plus you have Richard Benjamin as a hero!! Only in the 70s could a neurasthenic Jew ever be the action hero! The ending is pure chase (is there even any dialogue in the last 40 minutes?) but the set up earns this.
